How often should I water my lawn?

Watering infrequently and deeply is the key to a healthy Texas lawn. This technique helps plants grow longer, tougher roots that will allow them to access water throughout the summer even as temperatures rise.

How much water does grass need?

Typically, the average Texas lawn only needs about an inch of water per week, even in the hottest summers. If you’re unsure how long it takes to reach an inch of water, you can put a cup or can in your yard with an inch high marker and then time how long it takes to fill. In general, automatic irrigation systems disperse water at a much quicker rate than hose-end sprinklers. Start with shorter times and add additional time if large areas of damaged or dried-out grass appear. Of course, if there has been significant rainfall recently, you do not need to re-water.
